IMPROVEMENT IN FImsHING Loose-HINGE Bu'rs.

The Schedule referred to in -these Letters Patent :andl making part of the same.-

To all whom it may concern;

Be it known that we,ELLIs LUTHER, PLATT LYON, and WALTER EDWARDS, all of West Troy, inthe county of Albany, and State of New, York, have invented a new and useful Machine for Finishing Loose Buts; .and that the following isa full, true, and exact description of the construction and operation of the saine, reference being had to the accompanying drawings, wl'iicbionn a part of this specification, and in which-' Figure l, sheet l, represents a loose but prior to the operations hereinafter referred to.

Figure 2 shows the same as it appears when its parts are separated, as hereinafter mentioned.

Figure 1,lsheet 2, represents the trea'dle used for moving the revolving-shaft and burr.

Figure 2 shows the clamp for holding the wire, as hereinafter described.

Before the'buts are subjected to the finishing-pro-l cess which it is the design of our invention to facilitate, the two halves adhere to each other with great force.

' They have heretofore been drivenapart by hand.

The next step is to enlarge the cylinder which receivesthe wire. This has beendone by firmly fixing that half of the but in avise, anddriving a punch ordrift through the cylinder by hand.

The half' to which lthe wire is attached is then held firmly by hand against some solid object, and the wire is pointed by means of a revolving shaft and burr, simi-v lar to the one hereinafter described. Y

Our invention consists of' an arrangement for quickly and easily separating the different parts of the but by machinery, as hereinafter described and set forth.

It also consists in a devicefor enlarging the cylinder more effectue-ily and expeditiously than it- Vcan be done by hand.

It also consists .in the employment of a clamp for holding the wire while itis being point-ed, and a trcadle 1 for moving the revolving shaft and burr,- as hereinafter described and specified.

Having stated the nature of' our said invention, we will now proceed to describe the construction and-operation thereof, which are asfollows:

A represents a frame or work-table, to which 0in' machinery maybe attached.

B is a cog-wheel, which is actuated b v the shaft and pinion l.

. of' steel.

To points near the circumference of the last-men tioned wheels respectively are attached the hinizontal shafts D and G, in such a manner that the revolution 'of the wheels O (l will give tothe said shafts a to-andfro motion. v

The head ofthe shaft G is constructed-witha groove,

d, for the purpose of receiving the edgev of the but, as shown in fig. 4. i

.lust opposite the end of the shaft I) is placed the block F, constructed with the recess f.

At the end of the shaft Gr4 attached the drift H, opposite which is placed the block l, constructed with the recess y and the tube' li, the said recess being of tbe proper to receive the cylinder' b, fig. 2, sheet l, and the tube being a trifle larger than the drift, H. Lisa revolving shaft and burr, such as is commonly used for pointing the wire a of a loose but. Tliis'shaf't 'is moved up to the wire by the wedge It, and thrown back byv the spring fw.

S is a treadle, lwhich lowers the wedge R, and tis a spring, which returns it to its forn'ier position.

N is a groove, in which the wire c is placed whilet is being pointed', and A.

O is a clamp, which, when actuated b v the lever P, holds the wire firmly in the said groove.

' The operationv of our invention is as follows The operator takes the. but shown at fig. .1, sheet l, and-drops the leaf L into the recess f of the block F, while the leaf h will rest in the groove d of the shafthead E.' As thewheel B revolves, the shaft D will be thrown forward, and will drive the leaf h', with the cylinder b attached, off from the wire c, leaving the leaf' h on the top ofthe block F, while the leaf la drops into. a receptacle below.

The second operator takes the leaf h, and places it in the block I, so that the cylinder l) shall fit into the recess y. Then, by the further revolution of the wheel B, the shaft G is'thrust forward, and the drift H enters the cylinder b, and passes through it into the tube K, thus enlarging the said cylinder to the requisite extent.

It is desirable to inakethe'tube Kseparate from the 'remainder of the block, because the principal part of the wear cornes upon it, and it may be renewed when worn out, without procuring an entire new block. It mayr also he made of a harder material than the block. Thu'sthe block may be of wrought-iron,' and the tube Of' course it must fit tightly, so that it cannot be moved without the application of considerable force. ,i

The third operator takes the leaf k, and places the wire a in the groove N. Then, by means of the lever P, he moves the clamp O so'as to hold the wire' firmly in its place in the groove. Then placing his foot on the treadle S, he lowers the wedge R, which moves up the revolvingr shaft L, so that the burr M meets the end of the Wire a, and points it in the usual manner. Upon removing his foot om the treadle, the wedge R is raised'by means ofthe spring t, and the shaft L resumes its 'former position.

By means of our invention, We are enabled to dispense `with at least three-quarters of the manual labor heretofore necessary for these several -1nanipulations, and at the same time. todo the work much n'rore speedily and eiciently.

Having thus desciibed the construction and operation of our said invention,

What We claim` as new, and desire to secure by Letters Patent, is

l. The combination ofthe block F,- constructed with the recess f, with the reciprocatingshaft D and shafthead E, substantially in the manner and for the purposes herein described and specified.

2. The combination of the block I, constructed with the recess y, With the reciprocating shaft G and dri; H, substantially asa-nd for the purposes herein described und specified.

3. The tube K, in combination with the eiproeating shaft G, and drift H, substantially as and for the purposes herein described and specified.

4. The revoking shaft L, burr M, Wedge R, and treadle S, in combination with the groove N, cla'nlp O, and lever P, all arranged and combined substantially in the manner and for the purposes herein described and specified. 4 l

In Witness whereof, We have hereunto set our hands, this 26th daxY of August,'1868.
